What do people think grade boundaries are going to be like?
A few people on here are thinking mid-60's, I've seen 62 to about 67 hope that helps.

How did you all find it? People at my school have been saying that it was pretty bad.

I wrote: A wave that transfers energy, without transferring matter, as a result of oscillation. ::rolleyes:
:eek: That's like 3 out of 2, if only you could actually get that

I take pride in my definitions, considering I can't do crap all with the long answer ones
The only good page(s) was Kirchhoffs.

the wavelength was 3 cm though, so i thought 0.75cm was a quarter of it!! aaahhh am i wrong? how did you get half?
Because R moved 0.75cm from one transmitter and 0.75cm towards the other so the overall difference was 1.5 cm, spent ages on that one!

Oh my God. That's a disgusting question if you're right.

I feel so annoyed with myself, the paper wasn't even that hard but I ruined my chances by missing out almost 2 pages! I work so slowly sometimes, I feel like crying right now, I just need a C to get a B overall... hopefully we only need like half the marks for a C.

I would really appreciate if anyone could upload the paper if they have access to one.

I got the same for the first 2 but for out of phase I put W and X again I think, I'm probably wrong though I just thought Y and Z were 180 out of phase? :/
Oh i put x as being at rest and w with max speed, hmmm :/

Surely it was the difference moved along the wave, which was 0.75 cm, which is the wavelentgh divided by 4 which is the difference between a node/antinode. The difference moved from the transmitters should be irrelevant

i cant remember where all the letters were for the question on waves but i think the max speed was where the point had 0 displacement.
and the instantaneous rest was when it had maximum displacement.

Yeah, a lot of people on here. Infrared first?
I worked out the wavelengths and got it to be Uv light first i believe, the greater energy it had the smaller its wavelength so the shortest one was uv and the largest one was infra red
